The average tornado lasts 10 minutes.
However, tornadoes may last anywhere from a few seconds to over three hours, though tornadoes lasting this long are extremely rare.
A tornado that touches the ground is simply a tornado. Before it touches down it is called a funnel cloud.
Tornadoes can vary in width, but the narrowest tornadoes can be as thin as a few meters at the ground. These thin tornadoes are often referred to as rope tornadoes because of their slender and elongated shape.
Tornadoes can be associated with hail and heavy rain, but their formation does not involve precipitation. Tornadoes form from severe thunderstorms where strong updrafts of warm, moist air create a rotating column of air that extends to the ground.
A "double tornado" is scientifically known as a multiple vortex or multivortex tornado. In such tornadoes smaller vortices form within the main vortex of the tornado. These subvortices usually do not last long and individually do not impact the overall tornado very much. Rather than indicating a lack of organization in the tornado, a multivortex structure usually indicates a strong tornado.
Techincally, 100%. If it does not touch the ground it is not considered a tornado. The number of potential tornadoes that do not touch down is not known, as these weaker circulations are often difficult to detect.
Tornadoes can leave marks on crops, but it is rare for them to make marks in the ground itself. That usually takes a very strong tornado.
Tornadoes typically hit the ground, causing damage to structures and landscapes in their path. By definition, a tornado is a rapidly rotating column of air that extends from a thunderstorm to the ground.
Normally in the Spring and early summer. But tornadoes can happen all year long.
A tornado that touches the ground is simply a tornado. Before it touches down it is called a funnel cloud.
Usually tornadoes are found in the southwest quadrant of the thunderstorm, which is the updraft portion, usually at the back of the storm.
Yes, tornadoes do touch the ground. If the don't they are not considered tornadoes. However, in order to qualify the visible funnel does not have to reach ground winds, just the vortex of wind.

No. Tornadoes usually move from southwest to northeast.
Usually not for the people who experience them. Tornadoes are usually very scary when they hit.
Tornadoes are usually preceded by heavy rain and often by hail.
Tornadoes can lift people up, but they usually are thrown out of the vortex before being carried very high. Most of the people killed in tornadoes are struck or crushed by debris.
